We noticed that when you open a lot of files (i.e. project-wide search with multi-buffer) that the main thread can become unresponsive, because while we are async, we still load these files on the main thread. What this change does is it uses `smol::unblock` to load files on a different thread. Release Notes: - Improved responsiveness when loading files into memory.
